Peter is rumoured<b> to have broken up</b> with Mary.<br/><br/>1. Why do we use " to have broken up " instead of " to break up " ?<br/>Is it about the tense problem?<br/><br/>In addition, " The <b>full-page</b> advertisement in ABC was funded by donations from a web-based group ".<br/><br/>Why do we use full-page but not full-paged?<br/>Isn't it a hyphenated adjectives?
